To all wltom it may concern:

Be it known that ll, CHARLES MoVnE'rr, a

Ycitizen of the United States, residing at Cheltenham, in the county of Montgomery and State of Pennsylvania, have vinvented certain new and useful Improvements in Hot-Air Heating Systems, of which the fol,- lowing is a specificationt invention relates to improvements in heating system andmore particularly to hot air heating systems.

An object of my invention is to provide a re-circulating system of hot air heating based on the principle of a hot water circula-ting system employing feed and return pipes. The system is based on the principle that torfully an'deconomically heat a dwelling it is necessary to keep the air in constant circulation. When warm' airis discharged into a room at the registers at 1400, it circulates through the room or rooms giving off its heat units and due to transmission of heat through glass, exposed walls, etc., this temperature of the incoming hot air is reduced to about 65. turned to the heater through return pipes therefor and is refreshed with outside cool air through ducts leading to the base of the heater. The air is then reheated and recirculated.

A further object of theinvention is to provide a system of hot air heating, comining the coinventional pipe hot air system with outside cool air ducts, an air recirculating system using the rooms as radiators and a pipeless or one pipe system.

A further object of the invention is the provision of novel damper means whereby either of theforegoing systems, separately or in combination, may be utilibed to the advantage of the user.

A further object is to provide a heating system by which hot air may be directed into a single` room or 'led to a number ol' rooms, by a novel arrangement of parts.

With these and other objects in view the invention resides in certain novel` features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter boing supplemented by the accompanying drawwherein Figure 1 is a diagrammatical front eleva- M p p Iings 31 and 32 1n the oblique angular memtional view, partly in section, of my heating s stem insta led in the basement and three oora of 'a building;

Like numerals denote like out the drawings. y

Referring to said drawings in detail, the numeral 10 designates a heater of a conventional typeused for hot air heating purposesr having an outer shell or casing and an inner Shell or radiator and an air thoroughfare or passageway therebetween, provided with a base 11, a bonnet 12 and a main outlet pipe 13 to a irst'fioor register 14. From said bonnet 12, hot air outlet pipes 15, 16, 17 and 18 are provided in the usual manner for conveying hot air from said heater 10 to variparts throughhot air pipes 16 and 17 are shown in Fig. 1 extending vertically through the partition Walls of rooms in the 'usual manner to supply hot air to rooms on the second and third floors, registers 21, having dampers 25 controlled by members 22 of said registers 21 being provided to regulate the volume of air to be admitted to the individual rooms of the building, or to pass therefrom. Pipes 15 and 18 may in like manner be connected with other rooms in the house.

Cool air ducts 29 and 30, preferably rectangular in form are provided paralleling either side of the outer casing of the heater 10 and in spaced relation thereto, and are lsecured by suitable connections to openings in the basell of said heater. Oblique angular members 29 and 30 connect the upper portions of said ducts 29 and 30 to the first floor register structure as illus-l bers 29 and 30 of the cool air ducts 29 and 30, as illustrated, and extend substantially.

horizontally and then vertically by means of the connecting pipes 23 and 24 in the side or other walls of the building, and are provided with like dampers 25 at the various fioor levels to admit the cool air circulating near the floor levels of said rooms to said pipes, whereby the cool air descends through said ipes and ultimately enters the heater 10. onnecting pipe 232 and 23a may like- Wise be extended to other rooms in the house.

A register 28 is provided. as shown. to admit cool air from the outside to the pipe 24 through the connecting pipe 242 whereby the outside air may be admitted directly to the duct 29, or in conjunction with the cool air descending from the upper rooms, the ingress of air from said register 28 being regulated 'by a damper 28f in the pipe 24. Similar means are employed to admit outside air to the opposite duct 30.

Damper-s 34 are provided to regulate the ingress of cool air to the ducts 29 and 30. Said dampers 34 have the extending handles 34 whereby they may be positioned in any desired plane. Dampers 35 are positioned in each of the hot a'ir pipes 15, 16, 17 and 18. ln operation: 1n use as the usual hot air pipe heating system the pipes 15, 16, 17 and 18 are connected up as above described, or such of said pipes as may be required to heat the rooms desired; the heat ascends through said pipes and the extensions thereof as indicated by the arrows and is admitted therefrom to the various rooms by means of the registers 21 and the dampers 25. Cool air is admitted from the outside by means of a register 28', through the pipe 242 to the extension 24 from the duct 29 through which it gains admission to' the furnace 10 and mixes with the heated air therein, aiding lcirculation and freshening the air; outside cool air is admitted to the opposite duct 30 in a similar manner by similar means.

1n use as a recirculating system the pipes 15, 16, 17 and 18, or such of them as are required, are connected as aforesaid. and the heat ascends therethrough and through the branches thereof, as indicated by the arrows; cool air descends from the upper floor levels through the connecting pipes 23. 23, 24 and 24, as indicated by arrows in 1, and the connections 31 and 32 to the ducts 29 and 30, from which said ducts 29 and 30 said cool air enters the heater 10 adjacent the base thereof and circulates through the air thoroughfare in said heater between the radiator and outer casing thereof and is heated by the radiation from said heater and mixes with the hot air in said thoroughfare. The pipes and their branches returning the cool air to said. heater, as aforesaid, have the combined arca of the air spaces or thoroughfaresA through said heater 10. llt will be noted that a space is provided between the outer casing of the heater and the ducts 29 and 30.` This is to prevent the cool air on its return to the heater from being heated b y radiation therefrom until said air has actually entered said heater. Cool aii may be admitted froinou'tside to the ducts 29 and 30, as hereinbefore described, to freshen the air in said ducts to aid circulation, if desired.

In use as a pipeless or one pipe hot air heating system, the dampers 35 in the hot air pipes 15, 1G, 17 and 18 are closed: the damper 33 is opened; the dampers 34" in the oblique angular members 29 and 30 are positioned so as to check the ingress ol air through the openings 31 and 32 and their connections. The hot air thereupon ascends through the pipe 13 and the register 14 and the cool air is returned to the heater between said pipe 13 and the register structure through the angular members 29 and 30- and the ducts 29 and 30 and circulates through said heater as hereinbefore described.

By closing the damper 33, whereby it acts as a closure or top to the bonnet 12, and opening the dampers 35 in the hotI air pipes 15, 16, 17 and 18. the hot air ascends to the upper floors and by positioning the. dampers 34 to check the air descending from the register 14 and to admit air through the openings 31 and 32, as hereinbefore described, the cool air is returned `to the heater and warmed and circulated. This method ol recirculating air has been found in practice to positively heat ardwelling in all parta thereof with less coal consumption.

By setting the dampers 25 at angles all rooms can be supplied with heat at the same time. By setting the damper 33iat an angle both the first and upper iioors can be supplied with heat at the same time. rlhe dampers 34', can be 'positioned to secure cool air from the register 14 and the circulating air pipes 23 and 24 and from the outside, or from all these sources at the same time.

A deflector 3G may be used in connection witlrthe pipeless or one pipe system to defleet the hot air ascending through the radiator 14 to two separate first tloor roonis. by positioning the register 14 beneath the partition wall of said rooms as illustrated in Fig. 1 and inserting the V-shapcd dcflector 36 in a recess cut in said partition.

The dampers 25, 28', 33, 34 and 35 are all of a similar conventional single valve type and can be positioned in the hot and cool air pipes to regulate the circulation ot both the hot and cool air as may be desired. Said dampers are particularly illustrated in Figs. 5 and 6 of the drawings. ln Fig. 5 the damper 25 is shown partly closing the hot air supply pipe (for example the pipe 20) wherehy a portion of the ascending heated air enters a room through the register 21 and the reniaining portion continues its ascent, while in Fig. 6 the damper 25 is shown entirely closing the hot air supply pipe so that all the ascending air must obviously pass through the register 21. In this way the ascending hot air may ,be admitted or retarded or partly admitted and partly retarded fromaparticular room or rooms. lin Fig. 4 the' valve portion 34 is shown positioned So as to admit cool air to the duct 30 from both the opening. 32 and the register 14:.

From the foregoing description, taken in connection with the 'accompanying drawings, the construction, means of operation andthe numerous advantageous features of the invention will be readily understood without requiring a more extended eX- planation.

Although, in the drawings, I have shown certain specific details of construction and 4 1n the preceding have described such details, it is obvious that I need not be limited thereto otherwise than to the extent to which the appended claim restricts me.

claim:

ln a hot air heating system for buildings, the combination of an air recirculating and a pipeless system, comprising a furnace, having an outer casing, an inner casing and an air thoroughfare therebetween, means forming a vertical warm air conduit therefrom, a register directly above said conduit, means forming la cool air conduit about said warm air conduit, Warm air pipes extending laterally and then vertically from said furnace through the partition walls of the building, cool air ducts paralleling the outer casing of said furnace and in spaced relation thereto, connections between said ducts and the base of said furnace and with the cool air conduit from the said register, whereby cool air is admitted to said thoroughfare, extensions to said ducts extending laterally and then vertically through the partition walls of the buildlng, means to admit air from the floor levels of the rooms in said buildings and from the outside thereof, to said extensions whereby the cool air descends through said ducts to said thoroughfare and is heated therein by radiation from the inner casing of said furnace and ascends through the said hot air pipes and the conduit from ksaid furnace and means to regulate the direction and volume of theflow of the ascending warm air, substantially as described.
